II Introduction
The Wireless Diagnostic Interface is a multi-brand device which comes with
the CANDO tool kit. It is designed to connect wirelessly with the CANDO
Display Tablet, as a vehicle communication interface (VCI) for vehicle data
transmission. Thanks to the wireless BT technology, with which you are
allowed to work freely around the vehicle.
This interface device can communicate with vehicles’ electronic control
units (ECUs), guaranteeing performance and speed that redefine multi-
brand diagnostics. The development of this interface has been focused on
reducing the communication time, and ensuring the tool is practical to use.
The CANDO diagnostic platform combines the VCI device and the display
tablet with technical information into ensuring quick and simple access to
the vehicle to perform comprehensive diagnostics applications.
2.1 Wireless Communication
The Wireless Diagnostic Interface supports BT communication. It can transmit
vehicle data to the CANDO Display Tablet without a physical connection. The
working range of the transmitter through BT communication is about 300
feet (about 100 m). A signal lost due to moving out of range automatically
restores itself when the display unit is brought closer to the VCI unit.
For detailed information about VCI connection with the CANDO display tablet,
please refer to the CANDO User Manual.
2.2 USB Connectivity
The VCI device also provides a direct connection to the CANDO display tablet
or a PC via a USB 2.0 full-speed connection. All of the electronics are
contained in the device shell, making it a compact and rugged vehicle
communication tool.
2.3 Power Source
The Wireless Diagnostic Interface operates on 12-volt vehicle power, which it
receives through the vehicle data connection port. The unit powers on
whenever it is connected to an OBD II/EOBD compliant data link connector
(DLC).
III Functional Description
The Wireless Diagnostic Interface device includes the cable and user
manual. Please refer to the CANDO User Manual for additional information.

IV Product Troubleshooting
This part describes problems that you may encounter while using the VCI
device.
4.1 Vehicle Linking Error
A communication error occurs if the interface device fails to communicate
with the vehicle’s control module when performing diagnostic procedures.
You need to do the following check-ups:
1. Verify that the ignition is ON.
2. Check if the interface device’s OBD II connector is securely connected to
the vehicle’s DLC.
3. Turn the ignition off and wait for about 10 seconds. Turn the ignition
back to on and continue the operation.
Verify the control module is not defective.
If these issues have been addressed, verified, and you are still having trouble,
please contact technical supports for assistance. Refer to the CANDO User
Manual for additional information.

necessary to solve specific problems and to ensure the VCI device is working
properly with the OEM software. If you are experiencing any problems
during use, always make sure that you have the latest device software and
drivers.
4.3 Update Online
This function allows you to update the software for the device through the
CANDO Display Tablet . Make sure the Display Tablet is connected to the
VCI d e v i c e .
